C# Return Values
Return Values
In the previous page, we used the void keyword in all examples, which indicates that the method should not return a value.
If you
want the method to return a value, you can use a primitive data type (such as int
or
double) instead of void, and use the return
keyword inside the method:
Example
static int MyMethod(int x)
{
return 5 + x;
}
static void Main(string[] args)
{
Console.WriteLine(MyMethod(3));
}
// Outputs 8 (5 + 3)
This example returns the sum of a method's two parameters:
Example
static int MyMethod(int x, int y)
{
return x + y;
}
static void Main(string[] args)
{
Console.WriteLine(MyMethod(5, 3));
}
// Outputs 8 (5 + 3)
You can also store the result in a variable (recommended, as it is easier to read and maintain):
Example
static int MyMethod(int x, int y)
{
return x + y;
}
static void Main(string[] args)
{
int z = MyMethod(5, 3);
Console.WriteLine(z);
}
// Outputs 8 (5 + 3)
